DTC P3147-239: Transmission Malfunction; DTC P3147-241: Transmission Malfunction: Procedure

WARNING: This page is about a different variant/trim than selected.
  1. CHECK DTC OUTPUT (ENGINE CONTROL SYSTEM) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
    4. Check if DTCs are output.

      Result

      Result Proceed to
      Engine control system DTCs are not output. A
      Engine control system DTCs are output. B
    5. Turn the ignition switch off.

    B → See step   10 

    A: Go to next step 

  2. CHECK DTC OUTPUT (HV) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
    4. Check if DTCs are output.

      Result

      Result Proceed to
      DTCs other than P3147-239 or P3147-241 are not output. A
      DTC P3147-240 or P3147-242 is also output. B
      DTC P0A1D is also output. C
    5. Turn the ignition switch off.

    B → See step   11 

    C → See step   12 

    A: Go to next step 

  3. CHECK CRANKSHAFT PULLEY REVOLUTION (SHIFT LEVER IN P) 
    1. Turn the ignition switch off.
    2. Move the shift lever to P and lift up the vehicle.
    3. Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
      WARNING:

      Do not turn the ignition switch to ON (READY) while performing this inspection. Be sure to turn the ignition switch off before performing this inspection, to prevent the engine from starting.

      NOTE:

      Engine compression causes resistance when turning the crankshaft pulley. Check if the crankshaft rotates smoothly (or if it is locked) by manually applying sufficient torque to turn the crankshaft pulley. The torque required to turn the crankshaft pulley should be the same as for a known good vehicle of the same type.

      Result

      Result Proceed to
      The crankshaft rotates. A
      The crankshaft does not rotate. B

    B → See step   9 

    A: Go to next step 

  4. CLEAR DTC 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
    4. Read and record the DTCs and freeze frame data.
    5. Clear DTCs and freeze frame data.
    6. Turn the ignition switch off.

    NEXT: Go to next step 

  5. CHECK ENGINE RACING. Refer to  PROCEDURE - Step 4 

    NG → See step   11 

    OK: Go to next step 

  6. CHECK CREEP MOVEMENT 
    1. Depress the brake pedal, move the shift lever to D, and release the brake pedal.

      OK

      The wheels turn (the vehicle creeps forward).

      HINT: 

      If the wheels do not turn and the reading on the Techstream shows DTC P3147-239, replace the hybrid vehicle transaxle assembly.

    NG → See step   11 

    OK: Go to next step 

  7. CHECK ENGINE SPEED. Refer to  PROCEDURE - Step 6 

    NG → See step   14 

    OK: Go to next step 

  8. PERFORM SIMULATION TEST 
    1. Perform step 3 and steps 5 through 7 again.

      OK

      The problem symptom is not reproduced.

    NG → See step   11 

    OK → See step   13 

  9. CHECK CRANKSHAFT PULLEY REVOLUTION (SHIFT LEVER IN N) 
    1. Turn the ignition switch off and move the shift lever to N.
    2. Lift up the vehicle.
    3. Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
      WARNING:

      Do not turn the ignition switch to ON (READY) while performing this inspection. Be sure to turn the ignition switch off before performing this inspection, to prevent the engine from starting.

      NOTE:

      Engine compression causes resistance when turning the crankshaft pulley. Check if the crankshaft rotates smoothly (or if it is locked) by manually applying sufficient torque to turn the crankshaft pulley. The torque required to turn the crankshaft pulley should be the same as for a known good vehicle of the same type.

      OK

      The crankshaft rotates.

    NG → REPAIR OR REPLACE ENGINE 

    OK → See step   11
